Do you really call "Coinapult" a solution? Do you seriously think that they really could survive holding a 79% loss on the books for over 6 months & still be able to pay commitments?
To (hedge) a 79% loss you need an alternative income source to support it. Located in Panama, I imagine they have so many other alternate income streams, really?
I wouldn't count on them fulfilling their commitments when the BTC price fluctuates wildly.
79% of what?
Anyhow, if you're concerned about their business model just ask them directly to explain it to you (before declaring them insolvent). IIRC they're active on this forum.
And they're not the only business that offers such service:
http://www.coindesk.com/first-glimpse-inside-halsey-minors-new-payments-platform-bitreserve/https://bitreserve.org/en/homepagehttps://bitreserve.org/en/statusBitReserve have offices in US and Shanghai, if Panama is not good for you.
ps I don't use neither Coinapult or Bitreserve, so I cannot vouch for any of them.
